Description

Technical Field

[0001] The utility model belongs to the technical field of edible fungus strain culture equipment, and in particular relates to an edible fungus liquid strain culture device. Background Art

[0002] The traditional method of culturing solid edible fungi strains is to use sawdust, corn cobs, cottonseed hulls, etc. as culture media, sterilize them at high temperature, and then inoculate them. The mycelium needs to grow for one or two months before it can be cultivated and used. This method has problems such as long cultivation cycle, poor quality control, and waste of manpower.

[0003] With the breakthrough of traditional solid culture methods of edible fungi, liquid culture technology has gradually become the mainstream. Liquid culture technology is to mix potato juice, bran powder, etc. in a certain proportion into a nutrient solution, and then carry out high-temperature sterilization, cooling, and inoculation. By automatically controlling the temperature, oxygen, and nutrients, the bacteria can grow rapidly in the nutrient solution. The culture cycle is shortened from the original one or two months to 7 to 10 days. It has the advantages of short culture cycle, labor saving, suitability for factory production, and high production efficiency.

[0004] However, the existing edible fungus liquid strain cultivation device has the problem that the stirring method adopts rigid stirring, which may easily damage the strains and affect the cultivation quality if not handled with care. At the same time, the oxygen is directly introduced, which leads to uneven dispersion and unsatisfactory dispersion effect, thereby reducing the overall cultivation quality of the strains. In order to solve the above problems, it is necessary to develop an edible fungus liquid strain cultivation device. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further specifically described below in conjunction with the accompanying drawings.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a liquid culturing device for edible fungi, including a stainless steel fermentation tank 1, which is equipped with an automatic temperature control mechanism, a feed port 2, a discharge port 11 and a transparent window 14, and this part adopts the existing technical structure of the fermentation tank 1. The automatic temperature control mechanism is mainly completed by the interlayer 6 (including the water inlet 62 located on one side of the lower end of the interlayer 6 and the water outlet 61 located on the other side of the upper end of the interlayer 6) and the temperature detector 4, wherein the feed port 2 and the discharge port 11 are used for adding various raw materials and outputting qualified materials, and the transparent window 14 is used to visually view the growth status of the liquid cultivars in the fermentation tank 1.

[0019] In order to reduce the difficulty of operation during production and provide a suitable and evenly dispersed oxygen growth environment for the liquid strains, the fermentation tank 1 is also equipped with an elastic stirring mechanism and an automatic oxygen control mechanism. Among them, the elastic stirring mechanism includes a stirring shaft 13, a stirring rod 7 and an elastic stirring sleeve 8. The elastic stirring sleeve 8 can perform elastic stirring on the material in the process of following the movement of the stirring shaft 13 and the stirring rod 7, so as to avoid the problem that the original rigid stirring method is very easy to cause damage to the liquid strains in the case of a slight carelessness in operation. Among them, the automatic oxygen control mechanism includes a vent pipe 10, a gas disperser 12, an oxygen detector 5 and a controller (not shown in the figure). The gas disperser 12 can provide a uniformly dispersed oxygen growth environment for the liquid strains through the oxygen detector 5 and the vent pipe 10 under the control of the controller. The vent pipe 10 is externally connected to oxygen or purified air. After the oxygen or purified air enters the gas disperser 12, it is evenly dispersed into the material from a number of evenly distributed pores on the gas disperser 12, and is further evenly dispersed by the elastic stirring mechanism to provide liquid strains for growth.

[0020] Specifically, the gas disperser 12 may adopt a grid-shaped pipeline structure in the prior art, and a plurality of evenly distributed air holes are provided on the pipeline, and the gas is evenly dispersed into the material through the air holes.

[0021] Specifically, a stirring shaft 13 is provided in the fermentation tank 1, and a driving motor 3 is provided after the upper end of the stirring shaft 13 extends out of the upper center of the fermentation tank 1. A plurality of stirring rods 7 are evenly and symmetrically distributed on the stirring shaft 13, and an elastic stirring sleeve 8 is sleeved on the stirring rod 7. The elastic stirring sleeve 8 includes an elastic sleeve 81 matched with the stirring rod 7, and a plurality of elastic columns 82 evenly and symmetrically distributed are provided on the elastic sleeve 81. The elastic stirring sleeve 8 is provided on the stirring rod 7 through the elastic sleeve sleeve 81, that is, the elastic stirring sleeve 8 is tightly sleeved on the stirring rod 7 through the elastic action of the elastic sleeve 81 itself, and the sleeve connection mode of the two is conducive to the later maintenance and replacement of the damaged elastic stirring sleeve 8. The elastic column 82 is a truncated cone structure with a thick inner end and a thin outer end, and the structure is stable and conducive to long-term use.

[0022] Specifically, a gas disperser 12 is provided at the bottom center of the fermentation tank 1, and the uniform dispersion effect is better after the gas is introduced from the bottom. One side of the gas disperser 12 is connected to a ventilation pipe 10 provided through the side wall of the fermentation tank 1, and an oxygen detector 5 is provided at the upper end of the fermentation tank 1. An electric control valve 9 is installed on the ventilation pipe 10, and the controller is electrically connected to the electric control valve 9 and the oxygen detector 5 respectively. The oxygen detector 5 detects the oxygen concentration of the gas in the fermentation tank 1 in real time and feeds it back to the controller, which analyzes and processes the detection data, and then controls the electric control valve 9 according to the analysis and processing results, thereby controlling the on-off or the amount of gas introduced to achieve the effect of automatic oxygen control.

[0023] Specifically, the controller of the automatic oxygen control mechanism can be designed as a whole with other control systems of the culture device (such as controlling the working state of the driving motor 3 , controlling the working state of the interlayer 6 , etc.).

[0024] After completing the above installation, the utility model can be put into use, and the nutrient solution and other culture materials are added to the fermentation tank 1 from the feed port 2. The elastic stirring mechanism starts the drive motor 3 according to the set requirements, the automatic temperature control mechanism starts the interlayer 6 according to the set requirements, and the automatic oxygen control mechanism starts the electric control valve 9 according to the set requirements. The three together provide a suitable growth environment for the growth of liquid bacteria in the fermentation tank 1. The growth status of the liquid bacteria can be visually viewed from the transparent window 14. After the cultivation work is completed, qualified liquid bacteria materials are output from the discharge port 11.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
